" .1 if SEBASTASTUTZ; 'OF P ITTSBURG, PENNSYLVANIA l i sp'ecinetntn'ftmingpari,er @mais materiale/1,059,nateajAngstigier;"appiitgtitnjniea I Be it known that 1, SEBAsTIANSTUTmof Pittsb'urg'ifrr the county 'fot' Allegheny and Sta'teof Pennsylvania, *halveinvented new and useful Coal andOre QVi/"aslling or Separating Machinery; fand I` do hereby 'declarejthat 4'the following' is a full, clear,` 'andlexactidescription ot' the same, reference being hadto tlleac companying' drawing, forming part of this specification, andot' which- Figure l represents a vertical section taken at a; a: of Fig. 3. Fig. 2 rcpresen'tsa vertical section taken at y y of Fig, 3, anda' @front view ot the machinery.""Fig- -3 represents a top view with a horizontal section through the steam-cylinder.

The combination and arrangement of the machinery differs from that shown in the application led by me on the 11th day of' April, 1876, in the following points:

' The plunger-box B is provided with a movable lining, b, which can at any `time be removed and replaced by a new one.

As a heavy piston is necessary to give the stroke, it wears the sides rapidly, requiring frequent repairs. The4 removable lining renders these repairs easy and inexpensive.

The box-shaped piston or plunger' P, which, in the arrangement described by the application ot' April 11, 1876, is liftedupward by the mechanism of a dierential cam,in the present case receives itsmovement directly by the ac- .tion of steam. For this purpose a single-actiing steam-cylinder. C, is adapted to thev top ofA the movable box b by means of two crossipieces, c c. V is the steam-valve; v, the inlet- ',pipe of the steam, and p is the piston of the steam-cylinder. The inlet of steam into the cylinder C is regulated through the valve' V :and the levers ll. A reciprocating movement iis imparted to the latter by means of two drivers, e e, iixed at the upper end of the piston' rod fr. As represented by Fig. 1 of the annexed drawing, both the piston p and the plunger P are in their lowest positions. are iixed upon a common piston-rod, r.

They The valve V has been moved ,upward by the upper driver e, and the port 'i is open to allow the inlet of steam below the piston p. But before this latter has reached the end of its stroke the lower driver e will push the lever l upward,'whereby the jvalve V-'is m'ovedfdownward, andtheescape of the steamfroni the inside of the `cylinder'i) to the outsidefand above the piston pis free. -The'heavyplunger Pis no longer sustained, 'and will drop down upon 4the jbodyfof water. The ,length'ofv the strokeor the height of" dropping down `off/the, plunger P cannbe varied'accordingto circumstances; This is-done easily b v-xing.I the upperdriver-e so that the valve V' isf moved down,` inl'order to allow the 'escape :of the steam before the piston'p has reached its high# est position.A buffer, E, provided' lwithI a steelorrubber spring, is' 'fixed' at. the bottom of the movable box b, by which the downward movement of' the plunger P is limited.

Below the sieve S, at the inside of the separator-box A, a curved partition, m, is added. This is done for greater convenince of cleaning out that part of the box from tine sulphur and slate, the mud sliding down more easily to the opening o, where'its outlet is effected automatically, and in the same way as described in theapplication tiled by me September 21, 1876, inthe Patent Office. The pallet a, for directing' the water upward to the sieve S, can be either stationary or movable.

The mechanism and arrangement for giving it different positions have been fully described in the above application of September 21, 1876, and needs no further explanation.

Another improvement of the separator consists in the insertion of a dry screen, f, into the channel F, and near the bottom of it. rlhis is done to separate the water from the delivered material before the latter has reached the elevator-buckets. .The material slides down upon the screen f,and comes through the opening g to the outside, while the water is let through the screen, and can escape by the opening g. i

The arrangement of the channel h for the outlet of the stones or heavier material is also different from the preceding ones, as will be seen by the inspection of Fig. 2 of the annexed drawing. Thus the separator-box A is provided with three different delivery-openings, g, g1, and g2,o11e for the washed material, one for the water, and one for the heavier stones, &c.

'. lhe operation of the machinery is as fo1 lows The material to be separated being brought upon the sieve S at the back end of the box A, is forwarded by the action of the water to the front, the lighter parts of it passing over the edge u into the channel F, where they slide down tothe elevator, while the stones or heavier materials are let out from time to time by the opening k into the chaunel h, and fall to the outside of the separator through the opening g.y e

In order to obtain a good separation of the material, the upward movement of the plunger P has to be made very slow, so that only the fresh water coming in through the pipe q shall till up the empty space below the plunger, and thereby prevent the suction of the water from the box A back again below the plunger, and allowthe lifted-up material more time to settle down by its own gravity. The plunger moves downward upon the water with a sharp percussive action in order to produce a strong current for lifting up the entire layer of material upon the sieve.

Concerning the usefulness of the invention, it will be readily seen that the erection of separators, worked directly by steam, will be much cheaper than others worked by means of in termediate mechanisms. Besides this, both the speed as well as the stroke of the machinery can be regnlated'and varied according to the material which is to be separated. This is very important, as it allows the separation of the greatest quantity possible. By the addition of the curved partition minside of the separator-box A, the cleaning is effected more easily, and thus time and money saved.

Having thus described my invention, what I claim as new is- 1. The box b, communicating with the separator-box A by a clear opening unprovided with a valve,and also communicating directly with the fresh-water supply through the pipe q,in combination with thebox-shaped plunger P and the steam-cylinder C, with its steam-v passages and valve-movement, as and for the purpose specified. I

2. The boxes AB, provided with the curved partition M and the outlet o, substantially as described, for the purpose specified.

3. The combination of the stationary sieve S and water-chamber A with the dam u, passage F, and dry screen f, and with the passagesh, g2, and g g1, substantially as described.
